The prognostic value of postoperative radiotherapy in right tumor for lung related death: based on SEER database and real-world data.

ABSTRACT:

Background

Postoperative radiotherapy (PORT) is a therapeutic strategy for patients with non-small cell lung cancer (NSCLC). Nevertheless, some studies suggesting PORT does not improve overall survival (OS) including Lung ART phase III trial. The role of PORT and high-risk groups need to be confirmed.

Methods

Patients from the Surveillance, Epidemiology, and End Results program (SEER) from 2004 to 2015 were eligible. Aged ≥18 years with stage IIIA-N2 NSCLC, accepted PORT or not were considered for the study. Cox regression analyses and multivariate competing risk model were performed. Propensity score matching (PSM) was conducted. Data from a single-center study in China were used for validation.

Results

In all patients with IIIA-N2 NSCLC, death from respiratory illness increased year by year, with right lung-related deaths accounting for the main proportion. In SEER database, PORT was detrimental for OS after PSM (hazard ratio [HR], 1.088; 95% CI, 1.088-1.174; P = 0.031), with a same trend for death from the lungs (HR, 1.13; 95% CI, 1.04-1.22; P = 0.005). Right tumor receiving PORT were prone to death from lung disease(HR, 1.14; 95% CI, 1.02-1.27; P = 0.018). In China single-center cohort, PORT was significantly correlated with deteriorated OS (HR 1.356; 95% CI 1.127-1.632; P <0.01), especially in the right laterality (HR 1.365; 95% CI 1.062-1.755; P = 0.015).

Conclusions

PORT was a risk factor for stage IIIA-N2 NSCLC patients, particularly with characters of right laterality, male sex, age ≥65 years, and advanced tumor stage. These patients are more likely to death from lung disease after PORT.

Project description:Background and objective: The prognostic value of circulating lymphocyte subsets in cervical cancer patients receiving postoperative radiotherapy remains unclear. This study aimed to explore the prognostic significance of these lymphocyte subsets in this patient population. Methods: Peripheral blood samples were collected from 101 cervical cancer patients prior to receiving postoperative radiotherapy. Flow cytometry was utilized to determine the proportions and absolute counts of lymphocyte subsets, including total T cells, CD4+ T cells, CD8+ T cells, natural killer (NK) cells, and B cells. The Kaplan-Meier method and Cox regression analysis were employed to estimate the overall survival (OS) and identify the key prognostic factors. Receiver operating characteristic (ROC) curves were generated to assess the predictive accuracy. Results: The survival analysis indicated that patients with a decreased proportion of NK cells (P = 0.02) or reduced NK cell counts (P = 0.01) exhibited significantly poorer overall survival (OS) compared to those with higher levels of NK cells. In univariate Cox analysis, both the proportion of NK cells (P = 0.025; HR, 0.33; 95% CI, 0.12-0.87) and NK cell counts (P = 0.015; HR = 0.28) significantly influenced OS. In multivariate analysis, the proportion of CD4+ T cells (P = 0.02; HR, 0.08; 95% CI, 0.01-0.72) and NK cell counts (P = 0.08; HR, 0.11; 95% CI, 0.01-1.37) emerged as independent prognostic factors. The areas under the ROC curves (AUCs) for NK cell counts in predicting 1-, 2-, and 3-year survival were 0.66, 0.76, and 0.68, respectively. Patients diagnosed with stage IIIC1 exhibited a significant reduction in both the absolute counts and the proportion of NK cells compared to those diagnosed with earlier stages, specifically IB3 and IIA. Conclusions: Our study found that pre-treatment levels of circulating NK cell counts and proportions serve as promising prognostic biomarkers for cervical cancer patients undergoing postoperative radiotherapy.

Project description:ObjectiveThe optimal adjuvant therapy for uterine sarcomas remains poorly determined due to its rarity and histological diversity. The purpose of the study is to explore and characterize the association between utilization of radiotherapy and survival outcome in patients with surgically resected uterine sarcomas.MethodsWe collected data regarding uterine sarcomas which were confirmed after total hysterectomy between 2010 and 2018 period from the latest version of the Surveillance, Epidemiology, and End Results (SEER) database. Initially, 1-, 3- and 5-year survival rate were calculated to predict potential risk factors and possible role of adjuvant chemotherapy and radiotherapy. Propensity score matching (PSM) and inverse probability treatment weighting (IPTW) technique were employed to balance confounding factors in the utilization of additional therapy. Multivariate and exploratory subgroup analyses were respectively conducted to evaluate the impact of adjuvant therapy on overall survival (OS) and cause-specific survival (CSS).ResultsA total of 2897 patients were enrolled in the analysis. Survival benefit at 1-, 3-and 5-year after initial treatment was observed in the group of radiotherapy given, however, poorer prognosis in the group of chemotherapy administration. Accordingly, chemotherapy was enrolled as a confounding factor when stratifying and matching patients by receipt of radiotherapy. Prior to and after PSM-IPTW adjustment, radiotherapy both demonstrated beneficial effect on OS and CSS based on multivariate analysis. Further subgroup analysis indicated radiotherapy improved OS and CSS among a subset of patients in stage II-IV, particularly with uterine leiomyosarcoma, tumor grade IV, bigger tumor size than 100 mm and even with chemotherapy administration.ConclusionsAdjuvant radiotherapy in uterine sarcomas after hysterectomy might be underutilized, and proper use of adjuvant radiotherapy combined with chemotherapy after surgery in advanced-stage and high-risk patients might improve survival.

Project description:IntroductionAlthough the Tumor-Node-Metastasis (TNM) staging system is widely used for staging lung squamous cell carcinoma (LSCC), the TNM system primarily emphasizes tumor size and metastasis, without adequately considering lymph node involvement. Consequently, incorporating lymph node metastasis as an additional prognostic factor is essential for predicting outcomes in LSCC patients.MethodsThis retrospective study included patients diagnosed with LSCC between 2004 and 2018 and was based on data from the Surveillance, Epidemiology, and End Results (SEER) database of the National Cancer Institute. The primary endpoint of the study was cancer-specific survival (CSS), and demographic characteristics, tumor characteristics, and treatment regimens were incorporated into the predictive model. The study focused on the value of indicators related to pathological lymph node testing, including the lymph node ratio (LNR), regional node positivity (RNP), and lymph node examination count (RNE), in the prediction of cancer-specific survival in LSCC. A prognostic model was established using a multivariate Cox regression model, and the model was evaluated using the C index, Kaplan-Meier, the Akaike information criterion (AIC), decision curve analysis (DCA), continuous net reclassification improvement (NRI), and integrated discrimination improvement (IDI), and the predictive efficacy of different models was compared.ResultsA total of 14,200 LSCC patients (2004-2018) were divided into training and validation cohorts. The 10-year CSS rate was approximately 50%, with no significant survival differences between cohorts (p = 0.8). The prognostic analysis revealed that models incorporating LNR, RNP, and RNE demonstrated superior performance over the TNM model. The LNR and RNP models demonstrated better model fit, discrimination, and reclassification, with AUC values of 0.695 (training) and 0.665 (validation). The RNP and LNR models showed similar predictive performance, significantly outperforming the TNM and RNE models. Calibration curves and decision curve analysis confirmed the clinical utility and net benefit of the LNR and RNP models in predicting long-term CSS for LSCC patients, highlighting their value in clinical decision-making.ConclusionThis study confirms that RNP status is an independent prognostic factor for CSS in LSCC, with predictive efficacy comparable to LNR, with both models enhancing survival prediction beyond TNM staging.
